Book orders for the bonds maturing in April 2020 amounted to RON755.9 million, but the ministry sold only the targeted amount.
The yield was lower than 2.88% at a similar bond sale on July 22.
The issue will be reopened tomorrow in a bid to raise RON45 million at a supplementary non-competitive sale.
So far in 2015, the ministry raised RON22.5 billion in debt auctions on the local market.
